South Central / Southeast ND (08/29/19)

Information from the South Central/Southeast region of North Dakota.

Based on NDAWN, the region’s total rainfall May 1 through August 26 ranged from 9.6 inches (Harvey) to 17.9 inches (Robinson), with the Carrington REC receiving 11.1 inches. During the current month (August 1-26), rainfall ranged from 2.1 inches (Edgeley) to 4.9 inches (Oakes). Daily water use by corn (emerged on June 1) during August 1-26 averaged 0.18 inch.

The region’s corn growing degree day units (GDDU) accumulated from May 20 to August 26 range from 1480 (Robinson and Wishek) to 1710 (Brampton and Oakes). This range is -240 to +10 GDDU, depending on location, compared to the long-term average for the period. May planted corn ranges from milk to dent stages (R3-5). While corn has good yield potential, it is our row crop at most risk to reach physiological maturity.

Carrington REC’s dryland barley variety trial averaged 61.5 bu/acre; 42.3 lb/bu; 10.7% protein and 83% plump. In contrast, the irrigated barley variety trial averaged 109.5 bu/acre; 46.1 lb/bu; 13.4% protein and 93% plump.

Winter and spring cereal crop harvest continues including spring wheat. Rainfall is hindering harvest progress and reducing potential of marketing high quality seed.

Dry bean is nearing or at physiological maturity (R9 stage). Soybean has developing seeds (R5-6 stages). Sunflower stages primarily range from ray-petal drop to backside of head losing green color (R6-7).

The Carrington REC’s Row Crop tour is today (August 29) with tour wagons rolling at 4:30 p.m. General topics include field status of corn and soybean; white mold management of dry bean and soybean; cover crop research in dry bean and soybean; and corn intercropping.
